Leslies Fresh 'N Clear Non-Chlorine Oxidizing Pool Shock

Experience rapid, potent water treatment with Leslie’s Fresh ‘N Clear Chlorine-Free Pool Shock Oxidizer. It eliminates contaminants in just 15 minutes, leaving your pool visibly clear and enhancing chlorine’s sanitizing capability without adding extra chlorine.

Product Description

Oxidizing your pool and spa is a crucial part of routine water treatment and maintenance. Non-chlorine shock provides all the oxidizing strength that you get with a chlorine shock, only without actually using chlorine. With Leslie’s Fresh ‘N Clear Chlorine-Free Pool Shock Oxidizer, 15 minutes is all you need for a “fresh and clear” pool or spa! Using 4% Available Oxygen, Leslie’s Fresh ‘N Clear eliminates non-living organic contaminants and prevents combined chlorine, or chloramines. This provides an increase in Free Available Chlorine which is what works to sanitize the water. Best of all, there’s hardly any waiting, so you can jump in and enjoy your pool and spa after just 15 minutes. Leslie’s Fresh ‘N Clear will not add any additional chlorine to the pool or spa but will help increase the capability of the chlorine sanitizer that’s already in the water. Leslie’s Fresh ‘N Clear is the perfect maintenance shock to help keep your pool and spa water clear and swim-ready!

Usage Directions for Swimming Pools

  • Broadcast the required amount of Leslie’s Fresh ‘N Clear uniformly over the surface of the water, adding two-thirds of the total dose over the deep end of the pool.
  • Apply with the circulation pump running to ensure complete distribution and good circulation.
  • For the initial treatment, to ensure “break-through” oxidation, use Fresh ‘N Clear at the rate of two pounds (2 lbs.) per 10,000 gallons of water.
  • Subsequent treatment for most residential pools with normal bathing loads must be made once per week at the rate of one pound (1 lb.) per 10,000 gallons of water.
  • For semi-commercial pools or pools with large amounts of non-living contaminants, more frequent treatment may be required.
  • Application must be made when no swimmers are in the pool, preferably at night. However, since Fresh ‘N Clear contains no chlorine, there is no extended waiting period before swimming may be resumed.

Please Note: DO NOT use Fresh ‘N Clear in biguanide treated pool water.
